Abstract

A sealing device is disposed between an outer member (6) and an inner member (3) with a flange portion (4d) in which the outer and inner members (3, 6) are concentrically disposed and rotatable relative to each other. The sealing device (8) comprises a core metal (10) fit to the outer member (6), and an elastic seal member (11) having a seal lip integrally fixed to the core metal (10). The seal lip has a side lip (13) elastically and slidably contacting the flange portion (4d), and an exterior lip (12) formed at the outer diameter side of the side lip (13) so as to extend toward the flange portion (4d). The exterior lip (12) has a projecting portion (12a) projecting toward the flange portion (4d).
